As you noticed, I decided to revert to using direct register writes to
avoid having the modem-control lines being toggled on open/set_termios.
So with a trivial patch changing the initial LCR settings your device
should now be supported.

It would still be interesting to know whether the features mentioned
above works. Testing that using the series I posted on Friday would be
preferred (but not required).

Thanks,
Johan
